ABSTRACT
The Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.

Palatal tremor and Kernohan-Woltman notch phenomenon are rare motor symptoms that can show up in patients with lesion in brain stem or cerebellum. Patients with palatal tremor accompany ataxia, internuclear ophthalmoplegia, dysphagia, dysarthria and Kernohan-Woltman notch phenomenon causes ipsilateral motor deficits. Although its rarity, these conditions exhibit unexpected symptoms as well as considerable disability, which can raise etiologic and prognostic concerns for rehabilitation team. These two motor symptoms are discussed in this review.
